Polymer Capacitors Computer Segment

KEMET Organic Capacitors (KO-CAP®) are solid electrolytic capacitors with a conductive polymer cathode, capable of delivering optimized solutions for today and in the future. The KO-CAPs offer low ESR, improved capacitance retention at high frequencies, and a broad dimension offering, from large case sizes to sizes as small as 2012-10. This KEMET KO-CAP portfolio supports the designers in innovation and technology.
